To ali wwm mail/'concern'. y. Be it known that i, HENRY J. FOSTER, a

State of Ohio, have4 invented a. certain new `and 'useful Improvement in' Demountable Rims', of which @he followingl is a. fuli, clear,

This invention .relates generally to a onev piece ransplit riemounaeble tire-carrying rim endN'it lies foriteobje'ct' io provide for the quiek and easy contraction of the rim for the purpose of planing or removing fille tire, 'and the equally easy restoration of the rim to its normal diameter and into operetive relation with the tirel Another object is to, utilize e part o'sucli rim operatino oleane-as (lrlvmg loge and' also as means 'for locking the rim omis against circumferential zuid ioterei movi;-`

" In Fig; 3l have indieated'in dotted lines the engagement of lever or tool with the lugs preparatory 4to contracting therini, and in Fig. 4 I- have shown the lever or tool as moved through an arcjof approximately 180- aiid also indicated the locked position Aof the rim in-its opened o1' contracted posij tion; and itivill be notedtliat the head of the lever is made with a rentrant angle H3 which permits the end ot' the rim carryingv the lug-(i to travel the proper distance. to `effect the locking of the rim in its opened Vor contractedV position.

As beforestated, the opening l is` elose'r to the center of the rim than the opening G and when tlielever is brought into engage- .inent with the block C as previously de-v scribed, this block is used. as a fulcruni for the lever and consequently during the initial y,

turning inovementot the lever the ends ot the rim'A are first circu'inferentially sepa-A rated slightly 4so that during the continuedL inward movement ofthe end of the rim carrying the block D. said end will entirely clear 'the opposite end of the rim, notwith-`4 standing the fact that the eut B is a straight and radial cut. The turning'movement ot' the` lever is continued until the laghi-block f D passes beyond the 'lng or block and as soon .as this hasbeen accomplishedthe rejsiliency of the rim tends to carry the inner or c'bntracted end of the riin toA itsl ultimate and locked position as shown in Fig. 4; the

i vout out portion of the lever head H3 permitting the base of thei'im to move inwardly a sufficient distance to eiiect a complete and safe locked position of the lrim i-n its contracted condition.

"When the rini has thus been contracted it is obvious that the tire can be quickly and easily placed thereon Aor removed therefrom.

In order to return the riin to its normal or expanded position, the leverv is turned back, and when the block D in its returnl vmovement passes the block C- the resiliency of the rim `will then act to facilitate the'closing operation and bringv the parts back to their normal position asshotvn in Fig. 3,

'and inasmuch as the plate. E with' lug D e-xtends beyond the transverse division B- and inasmuch as openingi-lr is farther removed from the center of the'frirrr th'afnthe opening F it is 'obvious that a locking engagement will be effected between .the overlapping lug aiiil the adjacent end of the rim, andA if de-' sired, a stud or pin I can'befplaced upon the interior of one end of the rim for the purpose of. engaging a socketor recess K in the projecting portion ofthe. plate. This will prevent any possible separation of the riin ends when the rim is not upon a Wheel body.

Furthermore when the ends ot a perfectly straight cut rimare locked together in this manner it will beiinpossible to haveany lateral movement of either rim end.

'of an actuating lever.

It will thns be seen that l provide an ex ceedingly simple construction of demountable tire-carrying rim. provided with driving lugs so positioned and constructed that by ineansof asimple lever the said rim can be quickly and easily contracted' and ei;- panded in order to render possible the quick and easy placement or removal of a tire han v ing an inextensible bead.

vHaving thus described my inventionwvhat l claim is:

l. A transplit deniountable tire carrying rim having' inwardly projetrting lugs conneeted thereto. said lugs being constructed for engagement with a tool, and so positioned ith reference to the split in said rim that the initial movement of the tool will vcause a circumferential separation ot' the ends of the rim.

2. A one-.piece tire carrying rim of. the flanged type traiisplit at one point, drivine lugs connected to the ends ofsaid rim, sai

lugs having openings parallel Witliitlie axis 'Kent distances from the center of said rim.

4. A onepiece tire carrying riin transplitI at one point, lugs connected to the ends of said rim, said lugs havi'ng transverse open ings adaptedl to receive4 spaced members of a wrench, both of said lugs being upon the saniegside Aof the transverse split.V

5. A oiiepiece tire carrying rim transplit at one point, lugs connectedto the ends of said riin, one of said lugs extending beyond the dividing split, both of said lugs havingv transverse openings adapted to receive spaced members of an operating lever.

6.i\ one-piece tire carrying rimsplit at 'one point, an inwardly projecting lug' attached to said rim adjacent said split, a lug attached tothe other end of the rim` and extending beyond said split, said lugs having j axial yapertures said apertures being diii'er ent distances from the center of the rim and sey adapted to receive spaced members carried" by an actuating lever.

7. A one-piece tire carrying riinidivided transversely at one .point,a plate attached to one end of the rim and extendingl beyond the division ofsaid rim, a driving lug carried by said plate at the projecting end thereof, a driving lug connected to the opposite end Aof said rimand spaced'tfrom the j first mentioned lug, said lugs having axial passages adapted to receive spaced members line, gadlygs' havng'a'xiavl openings,l spht but ai', diffrent ftlaony line' beingnegper @hamm than the In lwhekrgcf my" Afzne-piece fire Cayng' :da at', onefpnginwafkly -i "transversely ai; (me poings 1u :attached to. connecd to the 'ends 'said'inwvsa.r.d l j,y
